An investigation into alleged corruption at municipal zoning offices in the Athens region has uncovered evidence of large overseas bank deposits, real estate investments and cash purchases of artwork, according to a case file compiled by the Internal Affairs Service.

The file includes a section on suspected money laundering involving several defendants linked to the planning department of the municipality of Kifissia.

Investigators allege that the department’s former head and his wife, a former secretary-general of the Municipality of Galatsi, maintained bank accounts in Greece and abroad through the wife’s mother.

During a search of the mother’s home, authorities reportedly found a handwritten note referring to the transfer of €207,000 from a London bank to a Greek lender, an amount allegedly including funds belonging to her daughter.

Wiretapped conversations cited in the file also refer to plans to invest €300,000-€400,000 in real estate, including the construction of a house on the island of Kythnos.
